Fig. 3 is a valve control circuit, fig. 4 is a signal indicating circuit, fig. 5 is a power-off operation circuit, and fig. 6 is a signal output circuit, which are described in detail as follows:
introduction of elements: SA1 is a mode selection knob, corresponding to 7 in fig. 1, SA2 is a power-off operation knob, corresponding to 8 in fig. 1, KA0 is a commercial power indication relay, KA1 is a valve switch control relay, KA2 is a mode selection relay, KA3 is a valve full-on indication relay, KA4 is a valve full-off indication relay, KA5 is a fault relay, SB1 is a valve opening button on a panel, corresponding to 5 in fig. 1, SB2 is a valve closing button on a panel, corresponding to 6 in fig. 1;
introduction of a valve control circuit: considering first that the valve itself is not faulted, when the local control is selected, the SA1 is turned to the local, the buttons SB1 and SB2 are the only control sources, and the command of the remote control system is ineffective because the KA2 normally open contact is not closed. When a valve opening button is pressed down, a KA1 coil is electrified to attract and maintain, a valve opening signal is sent to a valve through a KA1 normally open auxiliary contact, the valve performs opening action until the valve is fully opened, a valve closing button is pressed down at any time, the KA1 coil is electrified, the valve opening signal is disconnected, a valve closing signal is sent to the valve through a KA1 normally closed auxiliary contact, and the valve performs closing action until the valve is fully closed;
when the remote control is selected, the SA1 is rotated to the remote position, the local control circuit is disconnected, the KA2 is sucked, the KA2 normally open contact is connected, and the instruction of the remote control system is the only control source of the valve action; when a valve control switch of the remote control system is closed, the KA1 coil is electrified to attract and maintain, a valve opening signal is sent to the valve through the KA1 normally-open auxiliary contact, the valve performs opening action until the valve is fully opened, when the valve control switch of the remote control system is disconnected, the KA1 coil is electrified, the valve opening signal is disconnected, a valve closing signal is sent to the valve through the KA1 normally-closed auxiliary contact, and the valve performs closing action until the valve is fully closed. Secondly, if the valve breaks down, the KA5 coil is electrified, the normally closed auxiliary electric shock is disconnected, the whole valve control circuit loses electricity, all control functions lose effectiveness, and adverse conditions caused by operation during the fault to the valve and the production process can be avoided.
Introduction to the signal indication circuit: as shown in fig. 4, the terminal L, N, common, fully open, fully closed, Fault are all power and signal terminals on the valve. The AC220V power supply output by the standby battery supplies power to the circuit, firstly, the power supply is supplied to the valve, and the valve can be ensured to still have power to execute the switching operation when the commercial power is disconnected; and secondly, supplying power to a switch indication relay and a fault relay of the valve, supplying power to each indicator lamp on the panel, and sending each state signal to a remote control system through the relays.
Introduction of a power-off action circuit: the com, open and close in the circuit are command contacts on the valve, and if the com and open are communicated, the valve executes actuating action until the valve is completely opened; if com is connected with close, the valve performs closing action until completely closed. Under the normal condition of the mains supply, the KA0 coil is electrified and sucked, and the opening and closing command of the valve is completely controlled by the KA1 and is irrelevant to the SA 2.
Under the condition that the commercial power is disconnected, the coil KA0 is disconnected after power is lost, and the opening and closing commands of the valve are controlled through the selection condition of SA2 and are independent of KA 1. For example, if power-off is selected, then once the utility power is turned off, com will be connected to close via SA2, and the valve will perform a closing action under the power provided by the backup battery until fully closed.
Introduction of a signal output circuit: the remote local state, the full-open state, the full-close state and the fault state of the valve are fed back to a remote control system in real time through KA2, KA3, KA4 and KA 5.
The use scheme is as follows: 1, taking the requirement of manual mode, the valve is closed when power is lost (normal power is interrupted); firstly, turning on a controller power supply, then turning a mode selection knob to a local mode, turning a power-off action knob to a power-off switch, finally pressing a switch button on a panel to execute switch operation according to needs, after the action is executed, turning on a corresponding indicator light, if a valve has a fault in action, stopping the action, sending an acousto-optic alarm signal, and feeding back a fault signal to a remote control system; 2, taking the remote control requirement and the valve is open when power is lost (normal power is interrupted); firstly, turning on a controller power supply, then turning a mode selection knob to a remote mode, turning a power-off action knob to a power-off state, finally executing switch operation in a remote control system according to needs, after action execution is finished, lighting a corresponding indicator light, if a fault occurs in valve action, stopping action, sending an acousto-optic alarm signal, and feeding back a fault signal to the remote control system; the remote control system can be a PLC, DCS, SIS and other systems.
And others: the power supply capacity in the controller is adjustable, and proper battery capacity is selected according to the power of the electric actuator of the electric switch valve; the controller can be arranged at a position which is convenient to observe and operate and is close to the controlled valve on the spot; the controller can select boxes with different protection grades according to the field conditions.
